I have a series of questions because I'm taking a plane trip to the west coast for a wedding where I'll be taking pictures of the wedding. 1. I will be using Drebel with lexar 512mb 40X CF which can store about 270 large JPEG files (which I'll be using), I need to get more storage, another CF, looking for 1gig card, but what exactly is the difference between the cheaper verison like the 24X compared to 40X? I know it's speed, but will it effect me taking wedding pics if I get the cheaper version? also, I saw a recent post for a link where a 1 gig Lexar 40X for 200.00 after rebate, but can't seem to find it, help. 2. I will be flying, and I will be taking my Trekker backpack with me, which lens should I take: a. 70-200 L IS 2.8 b. 200 L 2.8 c. 28-85 f3.5-5.5 d. 50 MKI e. Tonkia 28-70 ATX-Pro II 2.8 (just purchased used, which I need info on) f. 100 Macro and a 420EX flash. I know I can't take all of them with two kids, please advice. 3. Is there any concern taking all the equipment through the airport check points? 4. Is will be my first shot at taking wedding pics, any advice? Thank you all in advance.
